The wallet’s swaps on the chain, newest first, each with the token and its symbol. Keyset-paged: pass nextBefore back as before for the next page; nextBefore is null on the last one.

The list covers the raw tape only: the last few days the database keeps on these chains (about 3 on BNB Chain and Base, 7 on Avalanche today). window.fromTs is where it starts. Older days are counted in the wallet route named by olderHistory, as totals per token, not as a list. Say how far back the list goes when you show it.

wallet on a trade is the address the tape attributed it to; a swap sent through a router that the tape could not attribute is not in the list.
Trades under the chain’s ingest floor are not in the tape (BNB Chain: $100).

Chain-keyed data for Avalanche C-Chain, Base and BNB Chain, served from Chord’s rollup tables for the chain (every swap summed by hour, token and venue). Only the trade tape, the prints ticker and the wallet read raw rows, scoped to one token or one wallet and bounded.

Access. No key needed while the chain is public (all three are today). A chain whose tape is off, or that is not public yet, answers 400 UNSUPPORTED_CHAIN (“chain N is not served yet”) unless the request carries an X-API-Key; those answers are sent Cache-Control: private.
Ingest floor. Every count, volume and print covers trades at or above the chain’s floor, returned as ingestFloor. BNB Chain runs at $100 today; Avalanche and Base at 0.
Readiness. 503 NOT_READY until the chain’s rollup has run on this deployment; 503 CHAIN_DATA_UNAVAILABLE when the store cannot be read. Never treat either as “no trades”.

Parameters

Path Parameters

chain

required

string

Allowed values: avalanche base bnb arbitrum ethereum 43114 8453 56 42161 1

The chain, by key or id: avalanche or 43114, base or 8453, bnb or 56, arbitrum or 42161, ethereum or 1 (case-insensitive). Arc, Robinhood Chain and Monad are refused with 400 UNSUPPORTED_CHAIN and a pointer to their own routes.

address

required

EVM address, hex, case-insensitive.

string

/^0x[a-fA-F0-9]{40}$/

Wallet address.

Query Parameters

limit

integer

default: 50 >= 1 <= 200

Newest rows.

before

string

/^\d{1,12}(:\d{1,15}:\d{1,9})?$/

Exclusive cursor: the previous page’s nextBefore (ts:block:logIndex), or a Unix second.

Responses

200

application/json

object

chain

integer

wallet

EVM address, hex, case-insensitive.

string

/^0x[a-fA-F0-9]{40}$/

window

The span the list can cover. fromTs null = the chain has no raw day yet.

object

fromTs

Unix time, seconds, UTC.

integer | null

toTs

Unix time, seconds, UTC.

integer

history

Always raw: this list never reads the data lake.

string

trades

Newest first.

Array<object>

object

Unix time, seconds, UTC.

integer

Transaction hash.

string

/^0x[a-fA-F0-9]{64}$/

logIndex

integer

block

integer

token

EVM address, hex, case-insensitive.

string

/^0x[a-fA-F0-9]{40}$/

symbol

string | null

side

string

Allowed values: buy sell

tokenAmt

Whole tokens.

number

usd

number

priceUsd

number

dex

string

nextBefore

Cursor for the next page; null when this page is not full.

string | null

olderHistory

Path of the wallet route that counts the days before window.fromTs.

string | null

ingestFloor

The tape’s ingest floor. BNB Chain runs at $100 today; Avalanche and Base at 0.

object

minTradeUsd

Trades under this USD value (at index time) are not in the index, so every count, volume and candle covers trades at or above it. 0 = every priced trade.

number

history

Floors in force over time, oldest first. Empty when the chain was never floored. Raising a floor does not remove older, smaller rows.

Array<object>

object

usd

Floor in force.

number

fromTs

Unix time, seconds, UTC.

integer
